So, I have done in depth searching and cannot seem to find the information I need. I was hoping someone here can direct me... I am taking the ISA certification test in a few days and cannot seem to find the tree id species list for the PNW. I have found a list of both the interior and coastal, but am not sure if the test covers both or if it is region specific. I am taking the test in three days, so any help is appreciated. Im not too worried, as I recently completed my forestry degree, but just want to brush up on specifics and focus on their list. Thanks!!
